WhatsApp (officially WhatsApp Messenger) is an American social media, instant messaging (IM), and voice-over-IP (VoIP) service owned by technology conglomerate Meta.[13] It allows users to send text, voice messages and video messages,[14] make voice and video calls, and share images, documents, user locations, and other content.[15][16] WhatsApp's client application runs on mobile devices, and can be accessed from computers.[17] The service requires a cellular mobile telephone number to sign up.[18] In January 2018, WhatsApp released a standalone business app called WhatsApp Business which can communicate with the standard WhatsApp client.[19][20]
The service was created by WhatsApp Inc. of Mountain View, California, which was acquired by Facebook in February 2014 for approximately US$19.3 billion.[21][22] It became the world's most popular messaging application by 2015,[13][23] and had more than 2 billion users worldwide by February 2020,[24] confirmed four years later by 200 million new registrations per month.[25] By 2016, it had become the primary means of Internet communication in regions including the Americas, the Indian subcontinent, and large parts of Europe and Africa.[13]
